Preguntas frecuentes sobre Steel pools

What winter maintenance do steel pools need?

Steel pools do not need to be dismantled during the cold season thanks to the corrosion protection on their metal sheets. To keep the installation in perfect condition until the following spring, follow these straightforward technical steps:

Thoroughly clean the walls and floor of the metal pool, removing leaves and organic debris.
Adjust the water’s chemical levels and add a preventive winterizing treatment to the system.
Lower the water level below the skimmer to protect the pipes from frost.
Install a Winter cover for 4x3 meter pools, secured around the outer perimeter, to block sunlight and slow biological growth.

This procedure prevents premature deterioration of the vinyl liner and protects the galvanized steel sheet.

I have a dirt garden with a slight slope. Can I install steel pools directly on this surface?

It is not feasible to install steel pools on sloping ground without first carefully leveling the surface. Even a drop of just one centimeter causes the hydrostatic pressure exerted by the mass of water to be distributed unevenly, pushing the metal wall toward the lower side and causing the sheet metal to buckle or the reinforcing framework to break.

The manufacturer requires a firm, smooth, level base. To ensure the structure’s integrity, always excavate until you reach a level surface at zero grade, or pour a 10 to 15 centimeter thick reinforced concrete slab. Using loose sand to fill in uneven areas is not recommended because the pool’s own weight will compact it and throw the whole structure off balance.

What is the difference between steel pools and tubular pools?

The main difference lies in the perimeter structural rigidity and the lifespan of the materials used to contain the water. While a tubular pool holds the water with a textile liner suspended over hollow tubes, steel-wall models contain the water within a continuous perimeter of galvanized sheet metal treated with zinc.

This rigid wall provides greater mechanical resistance to external impacts and strong winds. It also means that, over the years, only the waterproof inner lining needs to be replaced, such as a Blue Gre liner Ø 350x120 for round pools, without having to replace the outer metal structure, significantly extending the life of the investment.

I want to buy a round metal-wall pool for my children. What filtration system do I need to keep the water clean?

For optimal filtration in a medium-sized metal-wall pool, a sand filtration system is essential. Basic cartridge filters often fall short at flow rates above 8 cubic meters, clogging easily during weeks of intense heat.

It is advisable to size the circuit with a complete system that ensures the entire volume is recirculated within a maximum cycle of 4 to 6 hours. A balanced, compact option for this type of pool is the Star 300 sand filter with pump, which filters suspended particles with infrequent backwashing and keeps the water clear without chemically overloading the pool.

How is the hydraulic circuit connected in above-ground steel pools?

In this type of structure, the hydraulic circuit runs through holes punched directly into the galvanized sheet-metal wall at the factory. The technical process requires a series of specific installation steps:

The vinyl interior liner is fitted, and the pool is filled with water to a few centimeters below the skimmer opening.
The double-sided sealing gasket is positioned, and the metal outer fitting is screwed into place, ensuring an even fit.
Carefully cut the skimmer opening and the circular hole for the return jet once the water pressure has stretched the membrane.
Attach the flexible corrugated hoses or semi-rigid pipes, measuring 32 or 38 millimeters, to the filtration unit’s suction and return inlets.

This arrangement ensures a watertight joint with no leaks around the perimeter.

I’m going to install an oval model in my outdoor patio. How much clearance should I leave around it from walls and fences?

You must leave a clear perimeter strip of at least one meter around the entire pool. For oval models, this clearance is critical because the structure has cross-braces or lower cross-ties that extend beyond the vertical wall to counteract the lateral pressure of the water.

In addition to physically supporting the side legs, this service walkway allows you to maneuver during installation of the steel sheet, easily connect the skimmer pipes, and carry out periodic visual inspections of the perimeter fasteners. Always maintain a minimum clearance of two meters from overhead power lines and avoid placing the structure under dense tree cover to simplify daily maintenance.

How can rust and corrosion be prevented in outdoor steel pools?

Preventing rust depends on the integrity of the multilayer protective coating and careful handling during installation. The steel sheets undergo galvanizing and epoxy priming processes designed to repel the constant moisture of the outdoor environment.

The vulnerable point is usually located around the edges of the cutouts for the skimmer and return jets. When cutting the liner or tightening the screws, make sure the paint does not chip; if it gets scratched, immediately apply protective anti-corrosion enamel for metal. Also, clean up spills of chlorinated disinfectants from the upper edges of the frame profiles to prevent ongoing chemical damage to the painted surfaces.
